SPECIFICATION forming part of Letters Patent No. 455,175, dated J une 30, 1891. Application filed December 22,1884. Serial No. 150,940. A(ll'o model.)

To all whom, 7125 may con/cern:

Be it known that we, GEORGE OROMPTON and HORACE WYMAN, both of Worcester, county of Vorcester, State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a' specification, like letters and figures on the drawings representing like parts.

This invention has for its object to provide an improved construction of change shuttlebox looms, whereby the stop-motion on `the absence or breakage of the weft will not only arrest the picking mechanism, but also stop, and, if desired, automatically reverse the movement of the pattern chain or surface actuating mechanism.

One portion of this invention has for its object to provide mechanism whereby the loom when the weft is broken or exhausted will be automatically stopped and the pattern-cylinder reversed to automatically reopen the shed to enable the fault in the laying of the weft to be corrected. The feeler of the stop-motion in this our invention, as well as the dagger, is mounted upon and made movable with the lay in such manner that it is possible to detect a break or imperfection in the weft during the forward beat or movement of the lay, rather than as the lay reaches its extreme forward position. Detecting the faults in the weft while the lay with its reed is moving forward in the shed in which the fault occurred enables the lay by but one forward movement to actuate devices, which will be described, to effect the disengagement of the mechanism which actuates the pattern surfaces or chains, and, if desired, to arrest the latter as or just before the lay reaches its forward position. The stopping of the pattern surfaces or chains is effected, as herein provided for, during or just before the lay completes its forward movement, during which time the mechanism for operating the pattern surfaces or chains is disengaged from the control of the crank-shaft to thus prevent further forward rotation of the pattern surfaces or chains notwithstanding the further rotation of the crank-shaft due to momentum. As the pattern chains or surfaces controlling the order of movement of the sh edforming and of the shuttle-boxmechanisms are connected to rotate in unison, it follows that the arrest of the pattern chain or sur- .face for controlling the order of the sheds also effects the arrest of the pattern chain or surface which controls the order of selection of the various shuttles, this unison of movement always insuring the introduction of the proper filling into the shed originally designed to receive it. To avoid the picking of the shuttles in the movement of the loom due to momentum, as stated, after the disengagement of the usual shipper-lever from the usual holdingnotch in the holding-plate, the picking-sticks are disengaged from their actuating parts just as the shipper-lever is released, thereby preventing the throwing of a shuttle after the weft breaks. By.v locating the feeler of the stop-motion and its operating-dagger at or near the center of the lay the operation of the parts is rendered more certain and the mechanism is greatly simplified, one feeler serving 'to detect faults in the weft coming from either of the change shuttle-boxes. The time of operation of the brake of the other parts of the stop-motion is such that the brake when applied stops the loom with the shed open.

Figure l is a broken front elevation of a loom embodying the invention to bel herein claimed, the shuttle-boxes at the left of the loom and the lay and one of its swords and the several shafts being broken out to show the parts behind them, the parts omitted being old and common. Fig. 2 is a detail showing a portion of the lay at its front side with part of the weft stop-motion devices attached. Fig. 3 is a partial left-hand end elevation of Fig. l, the frame-work being' broken out at places, the said figure showing one shed-forming lever of common form. Figt is a detail to be referred to of the weft stop-motion de vices, the lay and breast-beam being in section. Fig. 5l is a planY view of Fig. 4 with the lay and its attached parts removed, the breast-beam being broken away to expose the parts immediately below it. Fig. 6 is a longitudinal section of the dog of the weft-stopping devices in the line fr, Fig. 5. Fig. 7 isa longitudinal section of part of the holder for the dog. Figs. 8 and 9 are details in plan ICO and front end View of the dagger detached. Fig. 10 is a detail view taken from the rear side of the loom at the left-hand side to show the connection between the crank-shaft and the mechanism for moving the pattern surfaces orchains and the litter and depressor of the shed-forming mechanism. Fig. 11 is an elevation and section of the arm with which the picking staff or stick is connected, the said arm, as herein shown, being constructed to form one member of a clutch, which is disengaged to stop the picking. Fig. 12 shows like views of the xed part of the picking-clutch. Fig. 13 shows in elevation a sufficient portion ot' the right-hand end of the loom to illustrate the brake mechanism.

Referring to the drawings, the frame-work A, the lay B, shuttleboxes B2, shuttle-box rods g2, their guides n2, cam-shaft l), arms p thereon, rolls q q, carried thereby, the shoes s 011 the picking-shafts t, of which shafts one is shown, the picker-sticks b', their connected straps d and fr, the crank-shaft d, gears j t', (shown in full lines, Fig. 1 and by dotted lines, 'Fig 3,) bevel-gear f on the driving-shaft e, the latterhaving fast and loose pulleys g and h, the link k', the belt-fork f,its controllingrod g', lever fi', with which it is connected, the shipper-lever m to actuate it,^the rod s', joined to the shippenlever, the auxiliary shipperhandle t', connected therewith and pivoted at the opposite side ot' the loom, and the shipper-lever holding notched plate fr', the chain f3, and spring h2 are all substantially as in United States Patent No. 265,659, dated October 10,1882, where the like parts are distinguishedY by like letters, so the further speciiic construction of such parts need not be herein further described, except to state that the cranks of the crank-shaft and the lay B are joined by usual connectingrods B3.

The shaft 3, upon which is mounted the usual notched disks or wheels which receive the pattern-chain y for the shuttle-boX-actuating mechanism, as well as the pattern-chain for the shed-forming mechanism, which will be hereinafter referred to, the gears D16 D15, upright shaft D, gears D8 D9 D7, shaft Dietarwheel D4 thereon, pin-wheel D3, toothed hub D10, arm D12, slide-rod D13, and'lever a2 to move the said rod are all common to United States Patent No. 264,864f, dated September 26, 1882,y

wherein like devices designated by like letters are employed to effect the reversal ot' the shaft D14 and pattern-shaft 3 without reversing the direction of rotation of the usual crank-shaft.

Herein it has been considered unnecessary to illustrate any of the mechanical devices located between the shuttle-box rods and the patternchain y which controls the extent of movement of the said rods to place the proper cells of the series of shuttle-boxes (to be 1ocated, as usual, at each end of the lay) opposite the level of the race of the lay, as any suitable well-known mechanical devices for such purposes maybe used. It has also been considered unnecessary to show more than one shed-forming lever and a piece of one `harness-frame to control the harnesses and effect the formation of sheds in the warps, for this invention does not require any novel form ofshed-forming devices.

'lhis invention is not limited to the employment of any particular devices for producing the movement of the shuttlebox mechanism, nor for the formation of shedsin the warps; but in practice we may use the shuttle-box-actuating mechanism substantially as represented in United States Patent No. 281,842 and shed forming mechanism substantially such as represented in United States Patent No. 280,243,dated July 20,1880, it being understood, however, that both the pattern chains orsurfaces for determining the order of forming the sheds and of moving the shuttle-boxes will be on the same shaft as provided for in United States Patent No. 264,861.

The shuttle-box mechanism which we prefer to use, as well as the shed-forming mechanism which we prefer to use, is fully represented and described in English Patent No. 3,655, dated July 25, 1883, and in the present case we have designated by the figure 115, at the left-hand side of the loom, a link which in the said English patent is designated by the letter d, and in the said United States patent, No. 281,842, July 2-1, 1883, by the letter t. These two patents are herein referred to and their links d and t specified to enable one conversant with looms to see that to add the shuttle-box1noving mechanism to the parts represented in this application it would only be necessary to supply the shuttle-box mechanism of the said English patent, connect with it the link herein marked 115, and to provide the cam-shaft of the loom and loom-frame with gearing to turn the toothed cranks, as provided for in the said English patent. le have considered it unnecessary to illustrate all ot these old parts in the drawings of this present specification.

The shedding or harness lever o herein used, but one of which is shown, is the same as that marked by like letter in United States Patent NoqlSOat, dated July c20,1880,and it will be operated positivelyin both directions fto raise and lower its connected harnessframe, but partially shown in Fig. 1 by a lifter and depressor, all as fully described in the said patent, which engage hooked jacks pivotcd upon extensions of the harness-levers. The lifter and depressor are connected to rods u, and if. The rock-shaft 08, having the arms 00, to which these rods are attached, derives its movement from' an arm 108 and a link 101, joined to a link 102, the lower end of which is placed loosely on a pin 103, project ing from a crank 105,V attached to the usual crank-shaftd outside the loom-t`rame, the said links at their junction having a roller-pin IOO which enters an openfaced guide-boxl 106, suitably attached to the loom-frame, such devices being substantially shown in United States Patent No. 230,243, but designated by different characters.

In Fig. 1 the link 102 is broken off and the link 101 omitted. The crank-pin 103 is em-v ployed to communicate motion to the pinwheel D3, which is simply a crank having a pin 112 to engage the star-wheel D4 once during each rotation of the crank-shaft, thus moving the shaft D5 intermittingly. The swords 113 of the layB are pivoted, as usual, to studs of brackets on the loom-frame.

In Fig. 1 the lay-sword atthe left is broken out, as is also the lay. The race of the layB at or near its center is cut away or slotted transversely, as shown at 4, Fig. 2, and by dotted lines in Fig. 4. At its front side the lay has attached to it by screws 5 the stand 6, having ears to receive the pivot 7, on which turns the head 8 of the feeler-fork 9, a portion of the said head being connected by a link 10 with the dagger 12, having as its fulcrum studs 13, projected therefrom (see Figs. 8 and 9) and entering holes in the stand 6. The dagger 12 at its front end has a finger 14, which, when the weft is properly laid and the lay is being moved forward is held by the feeler and its link 10 above and so as to pass and not catch the shoulder 15 of the block 16,

pivoted at 17 on the holder or bar 18, which is guided between upright fianges of a guideplate 19, adjustably secured by bolts 20 to the horizontal shelf 21 of the bracket 22, in turn attached by bolts 23 between flanges of a plate 24, secured to the inner side of the breast-beam by suitable bolts 25.

The shouldered block 16 and the holder or bar 18 constitute what I shall denominate the dog.7 (see Fig. 6) bent downward, and that end thereof, being somewhat heavier than its other end, normally rests in the slot 27 of theplate 19 so long as the dog is kept pressed inward toward the lay by the broad end of the elbowlever28, pivoted on a vertical bolt 29, attached to the under side of the breast-beam fv, a spring 29 (shown only in Fig. 5) being connected with one arm of the said lever and with a stud 29 on the breast-beam, the spring and lever normally keeping the dog pressed in toward the lay.

The horizontal part 21 of the bracket, atf tached to the breast-beam, is provided with a slotted ear 629, with which is adj ustably attached by a bolt 30 a dagger-lifter 31, the top of which is made as a cam, and against which the toe 32 of the dagger strikes and bears while the lay is reaching its backward position or preparatory to the picking, the said dagger-lifter `effecting the lifting of the feeler-fork in proper position to permit a weftthread to be laid in the shed. As the lay moves forward after the picking, should the weft be at fault--that is, broken or absent-fi The block 16 has its inner end 26 the feeler is free to drop under. the action of the weight of the connected dagger, so that the point 14of the dagger engages the shoulder 15 of the block 16, and, acting against the said shoulder, carries the dog outward or toward the breast-beam or in the direction of movement of the lay; but the inner bent end 26 of the block, arriving infcontact with the fixed part 33 of the plate 19,'turns the said block and effects the release of the shoulder 15 from the point of the dagger, such releasel being effected before the lay, reaches its forward position.

Extended across the loom from side to side below, and at the rear of the lay when in its backward position, is a rock-shaft 35, having near the center of its length and in line with the feeler-fork an arm 36, which has joined to its upper end a latch 37, the hook of which is adapted to normally engage the outer thickened end 38 of the bar 18, as in Fig. 5'. As the bar 18 is moved outward in the direction of the arrow 34 (see Fig. 5) by the point of the dagger, the thickened end of the said bar acts to turn the elbow-lever 28 far enough against the action of the spring 29 to cause the short arm of the said lever to strike the collar 39, fast on the rod s', thus moving` the said rod in the direction of the arrow 40 to effect the release of the shipper-handle m. and the movement of the usual driving-belt (not shown) from the fa'st to the loose pulley. 1Vhile the lay is acting to move the dog out-- Ward and turn the lever 28, the said dog acts IOC againstk the catch 37 and causes the shaft 35 to be rocked in its bearings, so that the arm 42, at one. end of the said shaft and outside the loom-frame, (see Figs. 1 and 3,) is lifted. Lifting the arm 42 causes the link 43,`con

nected therewith and adjustablyjoined to the y,

bar 44, to raise the latter and cause it to strike and move the lever a?, before referred to, which, through the rod D13, causes the toothed clutch or hub D10 to be disengaged from the toothed hub of the bevel-gear D8, thus vleaving the shaft 3.of the pattern surfaces at rest, provided the movement of the lever a2 is only sufficient to carry the inwardly-bentouter end of the said lever (see Fig. 1) in position to leave itin the notch 303 (see Fig. 3) of the guide or hlder 305, the extent of movement of the lever a2 depending upon the position of the bolt 206 in the slot 207. Should the connection between the rod 43 and arm 44 be such as to move the` lever a2 far enough for its end to enter the notch 304, then the hub D10 will be moved far enough to engage the teeth at its opposite end with the toothed hub of the bevel-gear D9, thus making the latter drive the shaft D11-and turn it in the reverse direction, and that instantly and While the lay IIO is moving forward, such reversal ofthe shaft D14 enabling it through the bevel-gears D15 D1G toreverse the movement of shaft`3, which actuates in unison t-he two pattern-chains 'y y2, respectively, that carry the series of indicators which determine the order of movement of both the shuttle-boX-actuating,mechanism and the shed-forming mechanism.

The arm l2 (see Figs. 3 and 1) is provided with a laterally-projecting lug or pin 15, that as the said arm is lifted, as described, strikes against the rear side of a bent lever 46, attached to a rock-shaft 17, which in practice will extend from side frame to side frame of the loom, where it will be supported in suitable fixed bearings. Movement of the lever 46 by the arm 42 causes therock-shaft-l to be turned, so that a forked arm 48, attached thereto and entering an annular groove 49 of a sleeve 50 of a lever or arm 52, slides the said sleeve on the round hub 5l of a collar 58, which is secured on the picking-shaft t, the latter being oblong or other` than round in cross-section. The hub 51 serves as the fulcrum for the lever or arm 52, (see Figs. 1 and 11,) which latter is provided at one side next the hub 53 with a notched projection 54 for the reception of the projecting portion 55 of the hub 53,the latter being fixed to the pickin g-shaft by screw 56. The upper end of the arm or lever 52 has attached to it the link or device which at its outer end is connected in usual manner with and so as to move the picking'- stick to throw the picker and shuttle across the loom from one to the other shuttle-box.

The notched arm or lever 52 and the pro.

jecting portion 55 of the fixed hub 53 constitute a clutch to effect the stopping and starting of the picking-sticks. When the lever -16 is moved bythe arm 42, as described, the lever or arm 52 is moved toward the rear side of the loom, and the notched part thereof is disengaged or unclutched from the projecting portion of the hub 53, fixed on the picking-shaft, the arm 52 so released being left loose on the round hub of the collar 58, thus permitting the picking-shaft to be turned, but without vibrating the arm 52 and the pickerstick b. The shaft t is turned in the direction to move the picker-stick by the rolls q, which strike the shoe s, the rolls being connected with the arms p of the usual camshaft b.

The parts of the picking mechanism are in duplicate at each side of the loom and areoperated by the rock-shaft 47 and its connections. As the picking is discontinued, it is necessary to stop the action of the take-up mechanism, and to do this the lever 16 has a rod 57 attached to it, (see Fig. 3,) which is thrust forward to lift the detent 158 temporarily from engagement with the teeth of the ratchet-wheel 59, supported upon a bracket attached to the loom side and operated in any usual inanner--as, for instance, as in United States Patent No. 192,514. The latch 37,

,joined to the arm 36, is extended forward toward the breast-beam andbeyond a latchguide 70, having an edge 7l (see Fig. l) inclined downward and away from the bar 18 The latch-guide in this instance forms part of the plate 2l, attached to the breast-beam.

Vhen the loom is in regular operation, as described, the hook of the latch 37 is maintained in engagement with the outer end of the bar 18 by the pin 63 of the latch-holding rod 61, placed in a bearing 60, extended from the plate 24 below the breast-beam, the said rod 61 being connected with the collar 64 on the auxiliary shipper-rod 3'; but when the dagger moves the bar 18 sufficiently to knock 0E the shipper-lever and move the latch 37 and rock-shaft to effect the stopping and reversal of the shaft D the hook of the latch 37, the latter being released from the pressure against it of the pin 63 of the latch-holding rod 61, falls by gravity, and, sliding on the inclined edge 71, is moved laterally away from the end of the bar 18.

The pattern chain shaft and patternchain i/2 having been stopped, as described, or stopped, turned back, or reversed, the operator by hand will restore the levers a2 and 4:6 to their normal condition. At this time the lay is nearly in its backward position, and in this condition, if the weft in the shed then open is perfect and is to remain therein the loom is ready to be started and the lay to be moved forward; but in the described condition of the parts it will be understood that there is not a weft in position to resist the descent of the feeler-fork, for the weft for that shed has already been beaten in. So to provide for not stopping the loom as the dagger meets and engages the dog 16 during the first forward movement of the lay, after correcting the fault in the weft, it becomes necessaryto be able to move the rod s far enough to put the belt on the fast pulley without at the same time engaging the hook of the latch 37 with the outer end of the bar 18 of the dog until after the dagger in the outward movement of the dog is disengaged therefrom. This is accomplished by attaching to the rod s the slide-rod 61, moving in unison with it, the said slide-rod having the pin 63, that engages the latch 37 and places it in position to be engaged by the bar 18, so placed thereon as to come in contact with the said latch 37 only after the rod s' has been moved far enough to turn the shipper-lever into place to transfer the driving-belt upon the fastpulley, or, in other words,the said pin 63 will not commence to move the latch 37 to place its hook at the end of the bar 18 of the dog until in the movement of the loom and the` forward movement of the lay the dagger has been released from the block 16, further movenient thereafter of the rod s in the same direction completing the movement of the shipper-lever to engage the notched plate r', and also placing the hook of the latch 37 in engagement with the bar 18 of the dog. VVh'en the dagger in the forward movement of the lay is released from the dog, the spring 29', acting on the lever 28, causes the latter to immediately push back the bar 18 into its normal position.

The toothed gear. j on the crank-shaft is IOO IIO

provided at its rear side with a brake-seg ment 80,'which is secured to the said gear so as to project therefrom in a direction nearly opposite the direction of the cranks of the crank-shaft.

The lever 8l, pivoted at 82 at the loom side and extended forward close to the shipperlever, has its front end bent outward longitudinally, as shown at 83, and the said bent portion 83, located close to the rear side of the belt-shipper lever and shaped asV shown in Fig. l, is acted upon by a roll 84 on a stud S5, 'inserted in the shipper-lever, the said roll acting against the portion 83 after the shipper-lever has been released from the notched plate 7", causing the lever 8l to be turned on its pivot to lift theconcaved brake 86 of lever 8l and place it in position to be struck by the brake-segment during the rotation' of the crank-shaft, the brake and brake-segment being' so placed as to insure the Astoppage of the crank-shaft with the lay started a little forward.

The shipper handle or lever is knocked off when the moving lay is about two-thirds of its distance forward; but it is not desired at that time to immediately stop the crank-shaft. On the contrary, it is speciallydesired that the crank-shaft should be permitted to continue its rotation until the lay has been moved fully forward and returned to about its backward position or a littlebeyond with a shed open, and therefore the brake-seg ment 80 is so located that the brake-shoe will strike against it to stop the loom in the desired position of the crank-shaft with the shed open. During` this movement of the lay, after the shipper-handle has been knocked off and while the momentum of the parts is suiiicient to turn the crank-shaft and other parts, the pattern-surfaces will be turned back to open the shed next back of the one in 'which the fault in the weft occurred, provided, as before stated, the lever CL2 has been moved to engage the notch 304. Should it be desired to merely stop the pattern-chain shaft 3 at the shed of the broken weft, it will only be necessary to adjust the bolt 206 in the slot 207 so as to effect the movement of the lever a2 only far enough to leave the teeth at both ends of the clutch Aor hub D10 disengaged from the teeth of the hubs of the gears DSDS above and below the said hub, respectively.

The weft stopfmotion consists, essentially, of the Weft-feeler, its connected dagger and dog, and means actuated by the latter to release the shipper-lever. Y

The picking mechanisnifor each side of the loom consists, essentially, of the pickingshaft, the picking-stick, anarm 52, loose on the said shaft, and the hub 53, havinga projection 55 and fast on the cam-shaft, the projection of the hub engaging the notched projection 5t of the arm 52, thus forming a sort of clutch. I

The means to prevent the movement of the arm 52 with the picker-shaft consists, essentially, of the lever L16.

The pattern surface or chain actuating mechanism consists, essentially, of the shaft 3 aud'shafts and gears between it and one of theloom-shafts, as d, to rotate the said shaft 3.

lVe believe ourselves to be the first invent-v ors of afloom containing in its organization a weft-stop mechanism in which the feeler and dagger are both carried by the lay andwherein the parts of the loom are so organized and `combined that when the weft breaks the shipper will be released, and also the picking mechanism and the pattern surface or surfaces will be stopped automatically; and we do not therefore desire to limit our invention to the exact mechanism herein described, but instead may employ other usual and known equivalents.

Ve desire it to be understood that the automatic stopping of the loom and the reversal of the pattern surface or surfaces to leave open that shed next back of that in which the broken weft occurred is considered to be within thescope of our invention whether the said loom be of the close or of the open shed variety.

The lay, means to move it, the feeler and connected dagger attached to the lay, the breast-beam, the dog, means to support the dog below the breast-beam, the rock-shaft 35, the shaft (l, the pattern surface or chain, its shaft 3,1neans to actuate the shaft 3 from the shaft d, the said means containing aclutch or hub, the lever a2, means to connect it with the said hub, and means, substantially as described, between the said rock-shaft and lever to actuate the latter, combined with the latch connected with the said rock-shaft, a guide to support the outer end of the latch while the dog is moved partially backward and while the lay is first started forward ina shed already containing a weft, and with means to thereafter engage the said latch with the said dog, substantially as described.

S). The picker-stick 2)',the shaft t, means to rock it, the hub 53, fast on the said shaft and provided with the projection 55, the arm 52, loose on the said shaft and provided with the notched projection 54, the strap m, the arm 48, rock-shaft 47, and lever 4(5combined with the lay, means to move it, the feeler and connected dagger, the rock-shaft 35, its arms 42 and 3(5,the breast-beam, the latch 37, the dog, and means to support the dog on the breastbeam, all substantially as described.

10. The combination, in a loom, of the followinginstrumentalities, viz: the pattern surface or chain y2,the shaft 3 to move it-,means to rotate the shaft 3, the lay, a weft stop-motion in which the feeler and dagger are carried by the lay and the dagger operates a dog to effect the release of the shipper-lever, a shipper-lever, a lever to move the clutch forming a part of the means for rotating the pattern-surface, and means, substantially as described, to operate it automatically from the stop-motion to effect the disengagement of the said clutch to stop the forward rotation of the pattern-surface during` that forward IOO IIO

movement of the lay which effects the release of the shipper-lever, substantially as described. y

l1. The combination, in a loom, of the followinginstrumentalities,viz: the pattern surface or chain y2, the shaft 3 to move it, means to rotate the shaft 3, the lay, a Weft stop-motion in which the feeler and dagger are carried by the lay and the dagger' operates a dog to effect the release of the shipper-lever, a shipper-lever, a lever to move the clutch forming a part of the means for rotating the pattern-surface, means, substantially as described, to operate said lever automatically from the stop-motion to effect the disengagement of the said clutch to stop the forward rotation of the pattern-surface, picking mechanism, and means, substantially as described, under the control of the dagger to thereby automatically effect the stopping of the picking While the crank-shaft yet rotates, substantially as described.

l2. The combination, in a loom, of the following ins'trumentalities, viz: the pattern surface or chain ff, the shaft 3 to move it, means to rotate the shaft 3, the lay, a weft stop-motion in which the feeler and dagger are carried by th`e lay and the dagger operates a dog to effect the release of the shipper-lever, a shipper-lever, a lever to move the clutch forming a part of the means'` for rotating the pattern-surface, the adjustable link 43, and means, substantially as described, to operate the said link and the said lever automatically from the stop-motion to effect the disengagement of the said clutch to stop the forward rotation of the pattern-surface during that forward movement of the lay which eects the release of t-he shipper-lever, whereby when desired after adjustment of the said link the shaft of the vpattern-surface may be both stopped and reversed to place its indicators in position to effect the selection of the Warp for the opening of the shed next back of that in which the weft was broken, substantially as set forth.
